DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0021] The present utility model provides a Figures 1-3 kind of endodontic file for machine use as shown, which includes a working end 101 and a counting mechanism. One end of the working end 101 is fixedly connected with a connecting handle 102. When the endodontic file works, the connecting handle 102 is connected with the machine expander, so that the working end 101 can rotate to work.

[0022] In a preferred embodiment, the counting mechanism is arranged on the outer wall of the connecting handle 102. The counting mechanism includes a fixed ring 201 fixedly sleeved on the outer wall of the connecting handle 102. An annular scale 202 is arranged on the outer wall of the fixed ring 201. A movable ring 203 is movably sleeved on the outer wall of the connecting handle 102. An indicating arrow 204 is arranged on the outer wall of the movable ring 203. A rotating mechanism is arranged on the front surface of the movable ring 203. A positioning mechanism is arranged between the movable ring 203 and the fixed ring 201. After using the endodontic file once, by rotating the movable ring 203, the indicating arrow 204 is aligned with the next scale, and one count can be completed, so as to facilitate the staff to determine the usage times of the endodontic file and facilitate the subsequent use of the endodontic file by the staff. There are a total of 20 scale numbers in the annular scale 202, namely 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19. Every five scale numbers are in a group. Among them, the 0, 5, 10, and 15 scales are all set to be longer, and the 0 scale is the longest. And the scale order of the annular scale 202 is clockwise, so as to facilitate the staff to determine the usage times through the scale value pointed by the indicating arrow 204 on the annular scale 202.

[0023] Among them, the rotating mechanism includes a connecting ring 401 movably sleeved on the outer wall of the connecting handle 102. A clamping ring 402 is fixedly connected to the back surface of the connecting ring 401. The clamping ring 402 is sleeved on the outer wall of the connecting handle 102. A rotating groove 403 is opened on the inner wall of the movable ring 203. The outer wall of the clamping ring 402 is rotationally connected with the inner wall of the rotating groove 403. A limiting mechanism is arranged between the connecting ring 401 and the connecting handle 102. By sleeving the movable ring 203 on the outer wall of the clamping ring 402 and rotating through a bearing, the movable ring 203 can stably rotate relative to the connecting ring 401.

[0024] Among them, the positioning mechanism includes a positioning block 302. One end of the positioning block 302 is fixedly connected to the back surface of the movable ring 203. A plurality of positioning holes 301 are formed in an annular array on the front surface of the fixed ring 201. The number of the positioning holes 301 is the same as the number of scales of the annular scale 202, and the number of the positioning holes 301 is 20. Each time counting is performed, first move the movable ring 203 to separate the positioning block 302 from the positioning hole 301, then rotate the movable ring 203 to align the indicating arrow 204 with the scale value of the annular scale 202, and then move the movable ring 203 in the reverse direction to insert the positioning block 302 into the corresponding positioning hole 301, which can avoid the phenomenon that the movable ring 203 rotates automatically and improve the working stability of the counting mechanism.

[0025] Among them, the limiting mechanism includes a limiting block 502. The limiting block 502 is symmetrically and fixedly connected to the inner wall of the connecting ring 401. Limiting chutes 501 are symmetrically formed on the outer wall of the connecting handle 102. The outer wall of the limiting block 502 is slidably connected to the inner wall of the limiting chute 501. An extrusion mechanism is arranged inside the connecting handle 102. By limiting the limiting block 502 through the limiting chute 501, the connecting ring 401 cannot rotate on the outer wall of the connecting handle 102. At the same time, the limiting block 502 can slide in the limiting chute 501, which can limit the moving range of the connecting ring 401, so that the movable ring 203 has enough moving space for the positioning block 302 to be separated from the positioning hole 301.

[0026] Among them, the extrusion mechanism includes a movable hole 601 formed inside the connecting handle 102. The inside of the movable hole 601 is communicated with the inside of the limiting chute 501. A movable rod 602 is slidably connected to the inner wall of the movable hole 601. The limiting block 502 is fixedly connected to the outer wall of the movable rod 602. A spring 603 is arranged inside the movable hole 601. The spring 603 is arranged on the front surface of the movable rod 602. By connecting the two limiting blocks 502 through the movable rod 602, under the elastic action of the spring 603 and the connection of the movable rod 602 and the limiting block 502, the connecting ring 401 always has a tendency to move towards the position of the fixed ring 201, so that when the movable ring 203 is not subjected to a large external force, the positioning block 302 can be stably inserted into the positioning hole 301, thereby improving the working stability of the positioning mechanism.

[0027] Among them, cutting surfaces 701 are symmetrically formed on the outer wall of the movable ring 203. Anti-slip patterns 702 are arranged on the outer wall of the cutting surfaces 701. When the staff moves or rotates the movable ring 203, the fingers of the staff directly clamp the position of the cutting surface 701, which can increase the friction between the fingers of the staff and the movable ring 203 through the anti-slip patterns 702, so that the movement and rotation of the movable ring 203 are more labor-saving, thereby improving the operation convenience of the counting mechanism.

[0028] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
